Cambridge sets the boundaries after each series, so nobody knows them in advance. These are the real boundaries from past series, not a prediction.

Questions
How are the papers weighted?
The 0625 syllabus gives the multiple-choice paper 30%, the theory paper 50% and the practical paper 20%, and Cambridge’s overall boundaries are out of 200. So your multiple-choice mark out of 40 is multiplied by 1.5, which makes it out of 60. Your theory mark out of 80 is multiplied by 1.25, which makes it out of 100. Your practical mark out of 40 counts as it is. Cambridge doesn’t print these factors; they follow from the syllabus percentages. Tested against Cambridge’s own paper boundaries, they rebuild every published Extended A and C boundary and every Core C boundary from March 2021 to June 2026 to within a mark.
Extended or Core: which am I?
Your paper numbers say. Extended candidates sit Paper 2 and Paper 4 and can get A* to G. Core candidates sit Paper 1 and Paper 3 and can get C to G. Everyone sits one practical paper, Paper 5 or Paper 6. If you’re not sure which you’re entered for, ask your teacher.
Paper 5 or Paper 6: does it change anything?
Both are out of 40 and both count for 20%, but Cambridge publishes separate boundaries for each combination of papers, so choose the one you’re sitting. Paper 5 is the Practical Test (1 hour 15 minutes); Paper 6 is the Alternative to Practical (1 hour).
Why do the boundaries differ between variants?
Each variant is a different set of papers (the second digit of your paper code: 42 is Paper 4, variant 2), and Cambridge publishes separate boundaries for each. Choose your variant to compare against your own rows. With “Not sure”, each series counts once, at the median of its variants. March series have variant 2 only.
Can you tell me this year's boundaries?
No one can: Cambridge sets them after each series. The calculator shows the real boundaries from past series, so you can see how much they move and aim above the highest.
Where the numbers come from
Every boundary is from Cambridge International’s grade threshold documents for Cambridge IGCSE Physics (0625), March 2021 to June 2026: the same numbers as on the 0625 grade thresholds page. The paper weighting comes from the 0625 syllabus for 2026–2028. If a number here ever disagrees with Cambridge’s document, the document is right. Sitting 0972, the 9–1 version? Cambridge publishes its boundaries separately, so this calculator doesn’t cover it.
